BAKER STORM SASHCONSTRUCTION 2 Sheets-Sheet 2 Filed May 19, 1964 United States Patent3,229,434 STORM SASH CONSTRUCTION John A. Baker, Des Moines, Iowa(Industrial Park, lylalden, M0.) Filed May 19, 1964, Ser. No. 368,514 10Claims. (Cl. 52-408) This invention relates to improvements in what iscommonly referred to as combination screen and storm windows and moreparticularly to the construction and mounting of the storm sash.

In the use of storm windows of the above class, the satisfactoryelimination of drafts and frost penetration is a frequent problem andarises generally where metal to metal contact is present between stormwindow framing and the supporting frame structure to which it isattached, or where screws are used for securing the storm window sashstructure which permits the infiltration of frost as is well known.Various forms of insulation strips have been employed in different waysbut these, if sufliciently satisfactory, are generally quite expensiveand very often have not adequately solved the problem.

Accordingly, one of the important objects contemplated by this inventionis the provision of an improved storm sash framing or construction whichincludes a novel and efficient frost barrier protection not only betweenthe storm window and its supporting structure, but also between thestorm window and prime window, and which can be simply and easilymounted and removed without the use of any tools.

Another object herein is the provision of a storm sash framing for whichno screws are needed in attaching the same so that no holes are requiredto be drilled which would create an access point for frost penetration.

A further important object is to provide a storm sash construction ofthe above class which includes a novel snap-in, snap-out locking meansfor securing the storm sash to its supporting structure.

Still another object herein is the provision of what I call a vinylglazing strip which can be easily secured to or removed from the edgeportions of the storm sash frame so that there is no metal to metalcontact between such frame and its supporting structure.

To attain these objects and such further objects as may appear herein,or be hereinafter pointed out, reference is made to the accompanyingdrawings forming a part hereof, in which:

FIG. 1 is a front elevational view of my new storm sash shown mounted ina supporting frame structure,

FIG. 2 is an enlarged combined perspective and crosssectional view takenrelative to the line 22 of FIG. 1,

FIG. 3 is a crosssectional view taken on the line 33 of FIG. 1,

FIG. 4 is a perspective exploded view of this new storm sashconstruction, and

FIG. 5 is a view similar to FIG. 2 but showing a modification thereof.

Referring to the drawings, the rectangular window frame structuredesignated generally by the numeral is what I shall refer to as thesupporting frame for my new storm sash construction 12 shown in FIG. 4.Frame 10 may be of any desired construction and as preferablycontemplated here is of aluminum. It is adapted to be mounted in anopening of a building wall (not shown) in a well-known manner andincludes peripheral flanges 14 on all sides for overlapping attachmentto the wall at the outer side thereof. Frame 10 will also includechannels such as 16 and 18 about the top, bottom and side edges whichframe the central opening 20 in which there is generally slidablymounted the framed glass panes (not shown) known as the prime window. Noinvention is 3,229,434 Patented Jan. 18, 1-966 claimed in frame 10 perse and the prime windows referred to are not shown since they form nopart of this invention and are mentioned merely to point out the type ofwindow with which the storm sash 12 is used. Such windows as generallycharacterized above are also known as combination windows since it is acommon practice to provide some form of storm window therewith and forthis purpose, frame 10 also includes on its outer side relative tochannels 16 and 18 a suitable flange or shoulder 22.

For my purposes, as will later appear, I have provided flange 22 with anupstanding sidewall 24 as best seen in FIG. 1 that extends along bothsides 26 and 28 and the bottom 30 of frame 10 and at sides 26 and 28terminates at the top in a lip or shoulder 32 which is spaced aboveflange 22 and is undercut or notched 34 throughout its length. Betweenlips 32 across the inner side of frame 10 at top 36 there is secured ametal weather strip 38 that extends on a plane intermediate the plane oflip 32 (FIG. 3) and the plane of flange 22 represented across the innerside of top 36 by the thin head or shoulder 40 (FIG. 3). Across thebottom 30 between shoulders 32 and on the same plane as strip 38 is thehead 41.

With reference now more particularly to FIGS. 2 and 4, the storm sash 12includes a rectangular frame 42 formed with suitable window track means44 and 46 defining a central opening 48. It will be understood thatframed panes (not shown) will be slidable in tracks 44 and 46 in aWell-known manner to serve as a storm Window closure for such opening.Such panes, as well as those forming the prime windows as mentionedabove, may be of any desired design and are not shown since they areimmaterial to this invention which relates only to the construction ofsash 12 as it is concerned with mounting to the supporting frame 10. Inthis regard, frame 42 is provided with the peripheral flange on all foursides identified by the numeral 50 at the top, 52 and 54 at opposedsides and 56 at the bottom. The outer dimension of these flanges is suchthat they will rest on shoulder 22 of frame 19 within the confines ofthe sidewall 24 on the several sides of frame 10.

Thus far described it will be appreciated that there is a metal to metalcontact between flanges 50, 52, 54 and 56 and shoulder 22 and while suchmetal to metal contact is a common arrangement in combination windows, Ihave found that the elimination of such metal to metal contact providesa better frost barrier protection. Accordingly, I have used elongatedslotted vinyl glazing strips 58, 60, 62 and 64 for frictional slip-onattachment to the edge portion of the respective flanges 50, 52, 54 and56. Strips 60 and 62 are also formed with the respective dependinglongitudinal lips 66 and 68 (FIGURE 4) along their closed side whichrest on shoulder 22 whereby the flanges of frame 42 are supported inspaced relationship above shoulders 22 and correspondingly spaces sash12 away from channel 18 in frame 10 as best seen in FIG. 2. By thisarrangement, a window (not shown) which will be slidable in channel 18as mentioned may be more easily removed from the inner side of frame 10because of the spacing provided by lips 66 and 68.

With strips 58, 60, 62 and 64 mounted as described, sash 12 is placed onframe 10 as seen in FIG. 1 where the upper glazing strip 58 is wedgedbeneath the weather strip 38 and the lower glazing strip 64 will tightlyabut the inner side of the narrow head 41. Frame 42 is then locked toframe 10 by one of the novel aspects of this invention which includesthe two like elongated resilient vinyl or metal V-shaped locking strips70. By virtue of their V shape, strips 70 define an upper edge 72, and alower edge 74 that is provided with the outwardly turned lip 76. Lockingstrips 70 are placed in juxtaposition on the respective strips 60 and 62so that the open V end is toward the sidewall 24 and lip 74 is wedgedbetween the closed end of strips 60 and 62 as can be clearly seen inFIG. 2. In this position the normal spread between edges 72 and 74 ofstrip 70 is such that edge 72 can be pressed downwardly below lip 32 onthe sidewall 24 where it will, because of its resiliency, snap intoengagement in notch 34 and thereby adequately secure frame 42 to frame10. This, as can be appreciated, requires no screw holes where frostmight penetrate and also requires no tools either for mounting or forremoval. At the same time, the locking strips 70 add further insulatingprotection as can be seen in the drawings.

With reference now to FIG. 5, I have shown a variation for mounting sash12 to frame which eliminates the strips 60 and 62, and which mayeliminate strips 58 and 64, if desired, but retains the locking stripsimilar to strip 70 only in larger proportions for obvious reasons andwhich has like numerals primed relative to the strip 70. Thisarrangement, while generally satisfactory, permits a metal to metalcontact of frames 42 and 10 that is maintained reasonably tight bystrips 7t) although the full stripping of frame 42 as described above ispreferable and believed to be generally more eflicient for purposes ofinsulation. I

It is submitted that the invention shown and described is aptly suitedto achieve the purposes intended and is characterized by a combinationof highly useful and mutually cooperating elements that combine theirrespective and proportionate functions in accomplishing the objectssought to be obtained.

It will be understood that the phraseology employed herein is for thepurpose of description and not for limitation and that modifications andchanges in the construction and arrangement of this invention can bemade within the scope of what is claimed, without departing from thespirit and purpose thereof. It is thus intended to cover by the claims,any modified forms of structure or mechanical equivalents which may bereasonably included within their scope.
